I get the following error messages when trying to open a CD device (specifically, the Teac CD-ROM CD-224E) that has no media present: hda: packet command error: status=0x51 { DriveReady SeekComplete Error } hda: packet command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown This happens when a "start stop unit" command (0x1b 0 0 0 3 0 0 0 0 0) is sent to the drive to try to close the CD-ROM tray, but this drive doesn't have that capability (it's a slim portable-type CD-ROM), so it reports sense key 5 (illegal request) with asc/ascq 24/0. This is exactly how SFF8090i says it should respond. But ide-cd.c (in cdrom_decode_status() ) just sees sense key 5 and spews out an error. It then goes on to request sense data, and cdrom_log_sense() understands this error and doesn't log it. The patch, for kernel 2.6.20.4, suppresses this error message.
